Estrategia de Breakeven con Trailing Stop

Estrategia que demuestra cómo mover el stop loss a breakeven y luego seguirlo conforme el precio avanza. La estrategia entra en una posición larga y la gestiona en dos fases:

  1. Después de que el precio gana BreakevenPlus puntos, el stop se mueve a BreakevenStep puntos por encima de la entrada.
  2. Cuando el precio continúa con TrailingPlus puntos de ganancia por encima del stop, el stop sigue al precio a TrailingStep puntos de distancia.

La lógica es simétrica para posiciones cortas si se abre una manualmente.

Detalles

  • Criterios de entrada: Abre una posición larga en la primera vela completada.
  • Largo/Corto: Ambos (el ejemplo usa largo).
  • Criterios de salida: El precio cruza el trailing stop.
  • Stops: Breakeven y trailing stop.
  • Valores predeterminados:
    • BreakevenPlus = 5
    • BreakevenStep = 2
    • TrailingPlus = 3
    • TrailingStep = 1
    • CandleType = TimeSpan.FromMinutes(1).TimeFrame()
  • Filtros:
    • Categoría: Gestión de stops
    • Dirección: Ambos
    • Indicadores: Ninguno
    • Stops: Breakeven, trailing
    • Complejidad: Básico
    • Marco temporal: Intradía
    • Estacionalidad: No
    • Redes neuronales: No
    • Divergencia: No
    • Nivel de riesgo: Medio
